Four Lab Tests Your Doctor Isn’t Running (But Should Be!)
Feeling tired, bloated, or “off,” even though your labs look “normal”? You’re not alone. Most standard blood tests miss the bigger picture. That’s why I put together this guide.
Standard testing is designed to catch disease, not to show how your body is truly functioning. That’s why so many people are told everything looks fine when deep down, they know something isn’t right.

At Modern Endocrine, I believe your health deserves more than quick checkboxes. That’s why I created this free guide, Four Lab Tests Your Doctor Isn’t Running (But Should Be!), to show you the deeper answers that standard labs miss.
Inside, you’ll discover how these four advanced labs can uncover hidden hormone imbalances, gut dysfunction, poor recovery, and even your true biological age. These are the tests I use with patients who are tired of guessing and finally want clarity on what’s really driving their symptoms.
By the time you finish the guide, you’ll know why:
IGF-1 is a powerful marker for vitality, liver health, and recovery
The DUTCH test goes far beyond hormone blood work
GI-MAP reveals what’s really happening in your gut
TruDiagnostic measures how your body is aging on a cellular level

I’m Dr. Cassie Smith, a board-certified endocrinologist and founder of Modern Endocrine. My mission is to help you move past “normal” and toward optimal. These four tests are a starting point to uncover the deeper truth about your health—and give you the answers you’ve been missing.
